The Standing Rock Sioux Tribe won a significant victory today in its fight to protect the Tribe’s drinking water and ancestral lands from the Dakota Access pipeline.

A federal judge ruled that the federal permits authorizing the pipeline to cross the Missouri River just upstream of the Standing Rock reservation, which were hastily issued by the Trump administration just days after the inauguration, violated the law in certain critical respects.

In a 91-page decision, Judge James Boasberg wrote, “the Court agrees that [the Corps] did not adequately consider the impacts of an oil spill on fishing rights, hunting rights, or environmental justice, or the degree to which the pipeline’s effects are likely to be highly controversial.”
